Secrets

 * 1) Enter the building southeast of the starting point (open the left window and shoot the button to open the door). Take the lift up and open the west door. Use the computer in the bedroom to lower the bookshelf and go through to find a hidden office with shotgun shells, a box of shotgun shells, and a health bonus. (sector 199)
 * 2) In the western area, go down the steps until you see walls in the western rock that look like they have bodies inside them. Go into the right alcove and use the wall to lower it, then enter the passage and use the switch to lower a lift. Get on it to ride it up to reach a berserk pack and a megaarmor. (sector 1661)
 * 3) In the future area, head to the northwest room and use the terminal on the east side, then go to the west end of the room and south to a secret room with health bonuses and a megaarmor. (sector 650)
 * 4) In the future area, open the way to the dark hallway and enter the northeast computer room. Go to the east side to reveal a soul sphere. (sector 758)
 * 5) At the south end of the subway tracks, head north to the red door, but stop before you reach the intersection and open the west wall. You will reach the cage that had two shotgun guys and a chaingunner. (sector 2273)
 * 6) In the room with the yellow key and red rockets, use the switch at the rockets, then flip the switch to the south. Go back to the intersection where the red door is and through the door again, but head left this time to pick up an invulnerability. (sector 1296)
